Hi!

I have a question regarding the execution of the NIC (ti) driver.
 
The execution of the driver goes in an loop as long as there are elements
in the queue. However, how is this scheduled on the CPU?

Is the execution preempted when the transmit ring on the card is full and
when later reaching a certain "empty"-level restarted by a new interrupt, 
or....?
